Referring `now lto the ,drawings `in detail,

the reference numeral 6 designates the carl'nireter` considered as a Whole and 7 the float-controlled feed-chamber, Which may be or any .common construction ,whereby the f gas'clenejis maintained at aconstantlevelin the carbureter. f v

The carbureter comprises a casing 8 which has two enjd'cylindrical vparts 9, l() and intermediate conical part l1 Whose `ivalls lliars "upwardlyanjd provide agradual up-` wardly-increasing mixing chamber l2 Lwhich extends up into the uppe'rcylindrical end 9 'ofthe casing. I

[i The yloiver,cylindrical,end part has inwardly-directed flanges 13 let i at -opposite ends ,inl which are formed' a series of. open# Vings l5, 1K6, respectively ;v the openings 16 in the `lower flange' 14 serving as air-inlets While the openings 15 intheA upper flange -'adr'nit'both .air and jy vaporized gasolene or 'other volatilefluidpto the' mixing""chainber.r

the casing; rIlle circularcentral chamber'lS andthe annular chamber 19 serve as adivided carburetin'g chambenbutvit is to benn-` 'derstood` that under certain conditions the annular chamberse'rvesfolly as an airpassage, as Will presently appeanf 'j The feed-,chamber `7 has a feed-tube 21 extending t laterallyk therefrom which is" passed through -the carbureting chamber, for

fwhich `purpose"thel casing has bosses 22" at.

diainetrifcallyopposite points provided Withv U threaded ,bores opening into the annular chamber 19' andjthe tube 21 isfexternally threadedv to permi'tfof its being ,passedl through Said bores and throughthreaded integrally formed with y'the feed-chamber e e e openings in the ycenter tube 17 Whichaife alined with` said bores;y f The tube 2l isshown v and has a comparatively large bor'eff',en

tending fromy itsouter'enfd inivardto a Vpoint i at'` least past: the vcenter ofthe` carbureting chamber, aiid'vfroinz'said bore a smallangular passage 24 leadsto the interior of the feedclianiber, part ofVl said passage extending through the wall of said feed-chamber.

Entering the feed-tube 2l is a plug 25' is adapted to cooperate with the beveledA outer end ofthe feed passage 24, as at 27;

The en'd'of the plug is packed by means ofy packingmaterial 28 packed around the nee# dle-ifalve at the outer end of the plug by a gland29 threaded onto the "projecting end of" said plug which isexternally threaded atsuch point. The needle-valve has a kiiurled head 30 or other nieaiis for conveniently turning the same with a view of regulatingv the i'lowof gasolene to a well-or surplus fluid chainberl which the inner portion ofy the bore 23 forms-iv `@ne oi" more apertures 32 are providedfin the center tube 17 at a pointabove the. gas-V ol'ene feed tube 21` which connect the two portions of the carbureting-chamber, said apertures serving at times'` as rair-inlets for the center tube and at other times as inix-` ture outletsV for said tube.

` Theupper en dfof the casing 8 .is closed with,afi-'removable lid or cover.` 33 fastened in place in anyr approved manner; said lid or coverlliaving a threaded central opening 344 into `which vis threaded a combined guidei'od' and pressure regulator 35 having its lower portionreducediin diameter to form aslioulder Tfand having said lower portion smooth to. `guide a governor-valve 8S `which is; seated' againstithe upper flange or` wall 13" which separates the annular portion of` the carbuieting-chamber from the mixing chaiiiber. Said Lgovernor-valve comprises an inverted cup-like central portion 39 having preferably a central guide tube 40 extending downward from its upper end and an outstanding flange 4l at. its"lower end which normally closes the openings in the wall 1S., The central cup-like portion of said ialvejlias apertures 42 `in itsy side and end walls for the admission of the vaporized gasolene and air tothe mixing chamber.

Y Surrounding the guide-rod"l 35 isy a'coil spring-43 which` exerts its` pressure lagainst saidivalve by reason ofitslower end bear-4 iiigthereagainst and' the upperrend, against the shoulder on the guide-rod. The pressure ofthe spring against said valve is regulated byy turning the guide-rod in the lidor 'cover 33, and for the purpose of retaining saidfguide-rod iii any adjustedl position,` a jam-nut 44- is threaded thereon and iinpinges .f against said lid orcov'er. The flange 41; of thegovernor-valve Ais soinewhatfsinaller than the' internal dia-me# ter.Y of the asiiig 8 at'this point so that a slight annular' space :separates `the wall of the mixiiigeclia'mber at its lower endl from core into which is threaded the edge of said flange. Owing to the wall ofy the` mixiiigchamber flaring upwardly from its lower end the intervening space between the saine and the edge of the governor-valve gradually increases in size as thevalve moves upward so that a greater quantity of gasolene and air may pass up into the 'mixing-chamber above said valve, this occurring when thepengine increases its speed and the suction in the mixing-chamber created thereby is su'fhcientto overcome the resistance of the spring 43, thus automatically admitting diluting air l through the openings 15 and enlarging the passage'for the escape ofthecarbuietedair, thereby assuring a'proper explosive mixture for the engine at all times.

The gasolene wellr or surplus fluid chainw ber lrlias anopeniiig45 through its wall so thatr air passing' through the center tube, hasan aspirating eillectgA on said wellpor chaniber'and draws out 'thegasolene theren from, whicliis vaporizedby'tlie air currents and passes upy into the mixing-chamber with the air lthrough the openiiigs'r424 in the, governor-valve.

` The casingShasa mixture outlet-tube 46 which extends laterally from ,the cylindrical upperend, thereofaiidhas'a throttle-valve 47 therein whiclris herein shown as a bi'ittion serving the purpose. y is 4adapted for Kconnection in any7 suitable bers of aneii'gine. y l n in some types of automobiles certain ex- Amanner witlizthe ignition chamber` or' chainplosive engines are usedtliatlwill notj allow suiiicient room` to arrange the carbui'eter as i terfly valvey but may be anyl other construeV This outlet-tube shown in Fig. l with respect tothe float controlled feed-chamber, or the space prol vided for the carbureter will not permit of connection with the enginer when the mixturel outlet-tube is extendedy iiiA the direction 'sliowiiinfFig l, and in such cases the car ,bureter casing may be given aquarter turn to `bringthe airtube and the mixture outlettubezinto differentv position with respect tothe feed-chamber. To permit of this the carbureter casing has a pair of' diainetrical bosses 48 arranged in a plane at rightangle's tothe bosses Q2; said'bosses 48,A being internally threadedto. permit the gas'olene feed-A tube 21 to be threadedtherethrough. The casingV has therefore two pairs of inter nally threaded bosses through eitherpaii' of which the ,feed-tube 21 is passed' and the bosses not iiiiise for sucli purpose are closed with screw'plugs 49.

rlhe operation ofthe device is as follows t` -lVheii preparing to start the engine to which the carbureter is connected,- it must be ascertained that the needle-valve QG is in such relation tol its valve-seat that gasolene can flow fronithe float-controlledfeed-chamber 7 into` the gasolene well l'andwllien' once center tube and alsofthrough the openings 16 in the bottoni Wall of the annular-chamber 19, thence through said chaniber 'fand through the apertures 32 inthe'center tube, A. `the two currents of aircoinniingling in the upper end of said center tube vand acting e upon the gasolene-Well toycause an as'pirat-"l` i ing eltect upon the gasolene therein,` which'.l gasolene isdraivn therefroin and rpasses with theair through the kopenings inthe governor-valve, thence into the] mixing chainber and frein there into the .engine through theiniXture outlet-tube 46, the escape of the explosive-mixture thus created being regulated .by f the throttlevalve p47 lWithiny said outlet-tube.` When startinglthev vengine or WhenA the enginey is'running"` at :y 3e 'isthereby proportionatelyy increased, it acts',
